A connector for fitting on a printed circuit board wire wrapped terminal post. The connector has a contact finger which is spring biased against the terminal post, so that for several of the connector-post combinations, a ribbon cable can be held inserted between the contact fingers and their associated posts. The contact fingers make connection with the conductor of the ribbon cable. In another embodiment, the connector makes connection between a wire wrapped terminal post and a contact on the printed circuit board.

Flexible printed circuit connector

A miniature multi-impedance transformer module specially adapted for use in telephony. In the preferred embodiment a pair of multi-winding transformers and a coil are configured to have connecting pins projecting both above and below the bodies thereof. The upward projecting pins are inserted in a printed circuit board carrying a plurality of connectors in a predetermined array. This assembly is installed in a miniaturized case and potted in place with the lower projecting pins extending below a mounting surface of the case. The lower surface and the downward projecting pin are adapted for ready mounting on a second printed circuit board. The connectors at the top of the module receive shorting plugs for selectively connecting the windings of the transformers and coil to provide impedance matching in telephone equipment. The miniaturized board mounted modules are readily adapted for high density rack mount applications.

Miniature multi-impedance transformer module

The disclosure relates to a stackable electrical connector assembly which includes a pin connector and terminal block means. The pin connector includes a partial enclosure having a floor and a divider wall defining first and second aligned partial enclosures. Each partial enclosure includes a plurality of apertures extending through the floor which are arranged in a predetermined array and a wire connecting pin in each aperture extending forward of the floor and terminating within the floor in between the front and rear surfaces of the floor. A block portion is adjacent each partial enclosure and includes an alignment key and a cable clamp and holder for securing a cable to each block at a desired angle to avoid unnecessary bending of the cables. The terminal block means includes a pair of identical terminal blocks each having a plurality of wire connecting pins arranged in the predetermined array and a bracket for aligning and securing the terminal blocks together. The bracket has alignment slots which are adapted to receive the alignment keys of the pin connector block portions so that when the pin connector and terminal blocks are joined, the wire connector pins of the terminal blocks are aligned with the apertures on the rear side of the pin connector floor. As a result, each pin of the terminal blocks contacts an associated pin on the pin connector to interconnect the cable wires connected to the wire connecting pins.

Electrical connector assembly

A low profile relay having both coil and spring pile-up mounted in the same plane on its E-core. The E-core has two extended outer arms upon which the spring pile-up is mounted and a shorter center arm upon which the coil and bobbin assembly is mounted and which also forms the strike area for the armature. A C-shaped adjustable armature spring has brackets on each end of the arms into which the armature is snap fitted, providing an adjustable and detachable armature and spring assembly. A dust cover is mounted over the assembly with a hole above the coil to provide heat dissipation for the relay. The relay assembly is mounted on a nonmetallic friction fit bottom insulator for mounting on printed wiring cards.
